Summary:The Devonian dolerite sills and submarine lavas of W Cornwall have suffered regional and contact metamorphism. Plots of their trace-element contents show that they form three chemically distinct groups. They are tholeiitic and appear to be related mainly by different degrees of melting of a heterogeneous mantle. [A.H.]
